- described in the process herein claimed.

It is the object of my invention to destroy parasitic microtirganisms, particularly on living tissue without injuring the latter, by progressively evolving sodium hydroxid contiguous to said tissue, from and in a moist mixture of calcium hydroxid, sodium carbonate, aluminum sulfate and boric acid,

which, with the products of their reaction,

. limit and control the action of said evolved sodium hydroxid; whereby the growth of such organisms is inhibited and their sub-- .above described. However,- substances of equivalent characteristics may be employed. For instance, calcium oxid, soda-ash, borax and alum. It is also to be understood that in some cases it is desirable to omit one or the other of said substances, while in other cases-I may add to the mixture. some inert substance, incapable of destroying the active principles of the chief ingredients aforesaid. For instance, when a wound has been sterilized by myantiseptic it maybe desirable to fill the cavity with a dusting powder of less active power, as a dressing, in which case the original mixture may be diluted with calcium carbonate or other inert substance, which has no other effect in the premises than to act as a diluent for the Serial No. 778,428.

antiseptic. In preparing my antiseptic for dental purposes I prefer to dilute the mixture with three times its weight of calcium carbonate or other such inert substance.

- It may be microscopically observed that my ant septic has the eflect of progressively dissolvlng the microorganisms, by first disintegrating the outer shells thereof, thus freeing their contents consisting of small round cells which then separate in the field of vision and disappear as they are dissolved. My antiseptic has a similar disintegrating eifect upon the broken down tissues and pus cells. On the contrary it has a distinctively beneficial bio-chemical or tonic influence on contiguous and adjacent healthy tissues. Therefore, said antiseptic may be applied with particular advantage wherever there is a lesion or body fluids out of place exposed to bacterial infection or already infected. Said mixture maybe applied to'the injured tissues, either as a dry powder or asan aqueous mixture at various degrees of dilution, in accordance with the location andnature of the injury.

For application to the air passages in the nose, throat, and lungs in cases of pulmonary phthisis, pneumonia, catarrh and other parasitic disturbances so locatedv that the air alone can be used as a vehicle to reach the injured part, the mixture in the form of dry powder may be diluted by air, in which it is agitated in any convenient manner and inhaled. Thus applied the fine particles of the mixture settle upon the ab. \ormal' secretions or on the injured membrane. The

moisture from the latter progressively dis- Y which it is to be applied. The weakest I do not desire to limit myself to the precise proportions or methods of application of my antiseptic above described, as it is obvious that various modifications may be made therein without departing from the essential features of my invention as defined in the appended claims.

I claim 1. A process for destroying microorganisms on living tissue, without injuring the latter, which consists in progressively evolving sodium hydroxid contiguous to said tissue, from and in a mixture of calcium hydroxid, sodium carbonate, boric acid, aluminum sulfate and moisture, which, with the products of their reaction, limit and control the action of said evolved sodium hydroxid; whereby the growth of such organ isms is inhibited and their substance dissolved withinseam;

out deleterious efi'ect upon contiguous healthy tissue.

2. A process for destroying microorganisms on living tissue, without injuring the latter, which consists in progressively evolving sodium hydroxid contiguous to said tissue.

1 3. A process for progressively evolving sodium hydroxid, including the step of maintainingv moist a mixture of calcium hydroXid, sodium carbonate, boric acid, and

aluminum sulfate.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsylvania, this ninth day of July, 1913.
